Kling 2.5 Turbo (pro) A woman with a left-leg amputation at the lower third of the thigh swims by repeating the following movements: she extends her arms forward underwater and sweeps both arms backward underwater in a wide arc; simultaneously with the arm movement, she bends her right leg at the knee underwater and, when her arms are positioned to the rear, pushes forcefully against the water while straightening her right leg. Throughout this action, the left thigh stump remains stationary and invisible under water surface. Then she repeats the mentioned movements again and again. Do not attach the second leg to her.
